Foschini received the
B.S.E.E. degree from the
New Jersey Institute of Technology, the M.E.E. degree from
New York University and a
Ph.D. (1967) from the
Stevens Institute of Technology. In December 1962, he joined AT&T Bell Laboratories, where he has worked since. He has also taught at
Princeton University and
Rutgers University. Within the telecommunications engineering field, he is best known for his invention of
Bell Laboratories Layered Space-Time (BLAST), one of the first developments in
MIMO (multiple input, multiple output) wireless technology. This wireless communications scheme recommends the use of multiple
antennas at both the transmitter and receiver. By careful allocation of the data to be transmitted to the transmitting antennas, multiple data streams can be transmitted simultaneously within a single
frequency band — the
data capacity of the system then grows directly in line with the number of antennas. This represents a significant advance on single-antenna systems. Foschini's 1996 paper, not published until 1998,
"On limits of wireless communications in a fading environment when using multiple antennas",
[1] played a key role advancing
multiple-input multiple-output wireless systems. Shortly after that publication, in a technical memorandum for his employers,
[2] Foschini introduced the BLAST concept, which is one of the most widely examined techniques in wireless communications research today. Among his later contributions, the paper offering a simplified form of the original BLAST architecture, called
Vertical BLAST (V-BLAST),
[3] has also resulted in intensive international research efforts. In 2002, Bell Laboratories' patent on BLAST was named by
MIT's
Technology Review Magazine as one of five "Patents to watch". According to the
Institute for Scientific Information Foschini is in the top 0.3% of most-cited authors. His papers have been cited over 50,000 times, resulting in an H-index of 63 and an i10-index of 114. In 2002, Foschini received the
Thomas Alva Edison Patent Award, an
honor given to people from
New Jersey who have changed the world with their inventions; he has also received the Bell Labs Inventor's Award, Gold Award and Teamwork Award and holds the titles of "Distinguished Member of Staff, Distinguished Inventor" in the Laboratories. Before his work on BLAST, Foschini had already been elected a fellow of the
Institute of Electrical and Electronics Engineers in 1986, "for contributions to communications theory". Foschini received the 2008
IEEE Alexander Graham Bell Medal "For seminal contributions to the science and technology of multiple-antenna wireless communications." And the IEEE Eric E. Sumner Award in 2006. Also in 2008 he received the New Jersey Institute of Technology Alumni Achievement Honor Roll Award and the IEEE Communication Theory Committee Technical Achievement Award. On March 28, 2015, he received the Stevens Technology Distinguished Alumni Award for Engineering, and is part of the Stevens Institute of Technology top 150 in 150 years. In 2018, Foschini was honored as an
NJIT magazine Top Influencer from the Institution. In 2009, Foschini was elected to the National Academy of Engineering. On September 17, 2023 Foschini died after suffering from
Parkinson's disease for several years. ==Publications==
